RECEPTACLE CAP.

Applicationy led .May 1'?, 1921. Serial No. 470,409.

To all whom t may Conc/lm.'

Be it known that 1, lGARNnsT R. lllARTrN, a citizen of the United States7 and resident of Ridgefield Park, in the county of lergen and State of' New Jersey, have invented a new and improved Receptacle Cap, of which the following is a full7 clear, and exact descri tion.

lV y invention relates to a receptacle cap and more particularly a dispensing cap for a fluid within the receptacle.

In connection with the lling of recept-acles such as storage battery cells in which liuid must be poured, to a predetermined depth, it is a well appreciated fact that yconsiderable difficulty has been experienced incident to the fact that insufficient iiuid or an excess of the same has often been introduced into t-he receptacle.

This difficulty is true in various types of receptacles such as ink wells, etc., but the greatest objection has been experienced in connection with battery cells, it being understood that an excess of distilled water introduced into these cells will cause an ineicient operation of the same, while too small an amount of fluid will primarily permit the solution within the cell to include too great an acid agent, as well as increasing the danger of the plates becoming eX- posed due to the evaporation of the water in the solution, while the battery is charging.

rlhus my present invention has reference to a receptacle cap suitable for association with any desired type of container and by means of Vwhich primarily an operator may introduce just that amount of fluid with which a receiving receptacle should be filled.

Thus a fur-ther object of my invention is the construction of a device of. the character specified which will. not necessitate the utilization of a stopper or extraneous member for preventing an evaporationof the fluid while the receptacle with which it is associated is not in use.

Still another object of this invention is the construction of a cap for receptacles by means of which the receptacle may be inverted prior to the introduction of the inner end of the same into the receptacle to be filled without any danger of the fluid contained wit-hin said receptacle escaping.

Still another object of this invention is the provision of a cap which shallr be extremely simple in construction and which rmay be manufactured at a minimum ligure.

Reference is had to the attached sheetof drawings as illustrating `practical embodiments of my invention, and in these drawings it will be seen lthat-- Figure 1 is a sectional side view otl areceptacle having one form of' my cap applied thereto and showing the same associated with a conventional battery wall. i

Figure 2 is an end view of the cap as illustrated in Figure 1.

Figure 3 illustrates the said cap While in the act of filling a receptacle'.

Figuret shows a slightly diferentform of cap than that illustrated inthe preceding figures. l'

Figure 5 is an end view of-this latter type of cap, and

F igurel shows the same while in use and associated with a receptacle ofthe type illustrated in Figure v1.

Referring' now more particularly to Figure 1 it will be seen in the embodiment illustrated that the reference numeral 10 indicates the receptacle to be filled, in this instance a battery jar having plates 11 positioned within it. The said jar is provided in the usual manner with an extension and fillingopening' 12 by means of which the fluid contained within the receptacle 13 may be poured into the jar 10, the flow of fluid being regulated by means of my improved type of' cap.

As has been shown in Figure 2, as well as in the figure mentioned, the said cap includes a body portion 14 adapted to firmly embrace the outer end of the receptacle 13, an end wall 15 being provided, which end wall closes the outer end of the cap, with the exception of an opening 16 conforming roughly to a double key-hole'opening for a purpose hereinafter more fully specified.

Furthermore a pair of. lugs 17 are secured to the end wall l5 and extend outwardly therefrom to any distance whichmay bedesired, Thus assuming that a battery jar is to have its fiuid replenished the` lugs are made substantially equal in length to the depth of fluid which is to exist upon the plates 11, the dangers of not reaching or exceeding this depth being well understood in the art.

It will be found that by virtue of the peculiar construction of the opening 16 that the receptacle 13 may be inverted freely and fluid other than placing the lugs in contact with the upperedges of the plate.

The

kfiovvof Huid Will continue until the saine has reached the height shown in Figure 1, and upon this occurring it Will be obvious that a water sealwill be formed which will preclude any danger of the fluid exceeding rbeen described before, is illustrated in' cona predetern'iined depth.

'5 n Figure 3 the saine type-.of cap as has nection Witha ldifferent type of receptacle, such as an ink Wellf18, and as aforestated, indicates the position in which the receptacle 13 must be placed to exert a pouring of the `fluid Within the receptacle 13.

"ln some instances a certain amount of air might leak between the body 14 of the cap Y and the receptacle 13, and it will be found after this occurred that the fluid Within said receptacle would escape irrespective of the 'fact that the same were held in a vertical in verted position.

-VJith this in mind I have devised a 3 slightly different form of cap which may j, be utilized to advantage Where danger of f this occurrence exists, and reference is had to Figures 4 to 6 as illustrating this cap.

This latter cap includes a body portion 19 vvassociated in any desirable manner with the receptacle 13, the said cap being formed *with an end Wall 2O providing an opening 21 similar. However it will be noted that an enclosed body 22 is provided in this type of cap in lieu of the lug 17, and this body terminates in an end Wall 23 forn'ied with i an Vopening 23 corresponding to the open- 1 ing 16.

This type of capk acts vin the saine manner as'tliat laforedescribed with the exception that when the saine is held in a vertical inverted position the valve 25 co-operates with the seat '24 and prevents the escape of any fluid from the body 22, which fluid might flow through the opening 21. Thus the escape of fluid is doubly prevented, but as has been indicated in dotted lines in Figure 6 the flow may be started by inclining the cap and receptacle with. which it .is associated. Upon this occurring the valve 25 Will move fioingits shallow seat 24, as has been shown in dotted lines to a point adjacent the Wall 23 and body 22. The fluid will now flow to the depth desired, but upon the same being returned to its vertical position the valve 25 Will again close the opening of the Wall 23 and the 4flow Ywill cease.

Thus it Will be seen that I have' provided a cap by means of Whichall of the objects `isetforth in the preamble of this specification ma be. accomplished, and it will be understood7 that numerous modifications of structure might readily be resorted to Without in the least departing from the spirit of my invention, Which l claini as;

1. A receptacle cap including a body portion, an end Wall for said body portion, said end Wall being formed with an elongated opening including' longitudinal sub-divisionsy of different Widths. e

2. A receptacle lcap including a body portion and means forming apart of said body portion for preventing the flow of fluid through said cap When'the same is in a vertically inverted position, said means permitting of a flo-W' of fluid through an opening formed in said cap upon said cap being inclined beyond the vertical.

3. A receptacle cap including a body portion, an end Wallfor said body portion, sai d end wall being formed with an elongated opening, and means secured to said cap for permititng of the flow of fluid'through said opening' into a reccptacle'to only 'a'prede-l termined depth.

4. A receptacle cap including body portion, an end Wall for said body portion, said end Wall being formed with an opening, the edge o-f said opening defining substantially a. circle and a slot of less Width than the circle merging therewith and lugs-secured to and extending beyond1 said end Wall.

5. A receptacle cap including a body portion, an end Wall for said body portion, said end Wall being formed With an openinggrthe 'edge of said opening defining a substantially cruciform figure and means connected to said end Wall and extending beyond said opening.
